11:07:54 <kaz> topic: PlugFest plan - Matsukura-san
11:08:40 <kaz> -> https://lists.w3.org/Archives/Public/public-wot-ig/2017Oct/att-0010/Servients_TPAC2017_171011b.pptx Matsukura-san's slides
11:08:55 <kaz> matsu: 4-layer structure for PlugFest
11:09:30 <kaz> ... 4 layered servients: app, remote proxy, local proxy and device
11:09:42 <kaz> ... [Servients and protocols]
11:09:54 <kaz> ... generated a table on servients and protocols
11:10:06 <kaz> ... filled in with Fujitsu and Panasonic
11:10:08 <McCool> q+
11:10:39 <kaz> ... Application Servient, Remote proxy Servient, Local proxy Servient, Device Servient
11:10:53 <kaz> ... and interface protocols between them
11:11:00 <kaz> ... (goes through the table)
11:11:33 <kaz> ... (explains Fujitsu's example)
11:12:00 <kaz> ... air conditioner, LED and blind connected with http
11:12:07 <kaz> ... also another LED connected with HTTP
11:12:31 <kaz> ... can update the table if you can provide the information
11:12:41 <kaz> mm: similar table on the f2f wiki?
11:12:51 <Mizushima> Mizushima has joined #wot-pf
11:13:02 <kaz> ... which protocol on which side?
11:13:12 <kaz> https://www.w3.org/WoT/IG/wiki/F2F_meeting,_4-10_November_2017,_Burlingame,_CA,_USA#PlugFest_.284-5_Nov_2017.29
11:13:29 <kaz> matsu: if you support more than 1 protocol, please say so
11:13:37 <kaz> mm: question on the first page
11:13:54 <kaz> ... [Servients from participants on TPAC 2017 plugfest]
11:13:56 <mkovatsc> q+
11:14:04 <kaz> ... local proxy inside or outside of the local net?
11:14:14 <kaz> mjk: same question
11:14:28 <kaz> ... can also have some slide on that
11:14:41 <kaz> ... protocols could optimize the connection
11:15:17 <kaz> matsu: (moves the line of "NAT/Firewall" above the "Local Proxy Servient")
11:15:22 <kaz> kaz: think that was a bug
11:15:38 <kaz> mk: similar setup to Japan?
11:16:34 <kaz> kaz: do we really want to have 6 apps?
11:16:41 <kaz> mm: maybe interesting
11:16:58 <kaz> mjk: maybe everybody don't need to provide end-to-end system
11:17:10 <kaz> ... multiple applications are good for WoT
11:17:33 <kaz> ... for example, my application can connect with multiple devices
11:17:47 <kaz> ... that is a story we need
11:17:54 <kaz> kaz: +1
11:17:59 <kaz> mm: do you want to finish this first?
11:18:35 <kaz> matsu: yes (and move ahead)
11:18:45 <kaz> ... [High-level description of Issues]
11:18:54 <kaz> ... Fujitsu has identified potential issues
11:19:06 <kaz> ... also would like to hear your about your issues
11:19:14 <kaz> ... [Deadlines and plugfest schedule]
11:19:26 <kaz> ... (strawman idea on the schedule)
11:19:39 <kaz> ... Oct. 18: complete the table of "servient and protocol"
11:19:45 <kaz> ... who provide what?
11:20:07 <kaz> ... collection of TD for the servients for the plugfest
11:20:19 <kaz> ... clarify the application scenarios
11:20:34 <kaz> ... Oct. 25: specify inter-servient interface
11:20:57 <kaz> ... Nov. 4-5: Fujitsu open at 9am-6pm
11:21:11 <kaz> ... 1st day (Nov. 4): prep and plugrest
11:21:18 <kaz> ... 2nd day: plugfest in the morning
11:21:21 <mkovatsc> q-
11:21:24 <kaz> ... demo and discussion in the afternoon
11:21:54 <kaz> kaz: the scneario is something like Koster mentioned?
11:21:54 <kaz> matsu: yes
11:21:56 <kawaguch> kawaguch has joined #wot-pf
11:21:57 <kaz> mk: tx
11:22:09 <kaz> ... please put this as well on the plugfest repo
11:23:13 <kaz> mm: suggests @@@

11:24:35 <kaz> mm: added information to the wfiki table
11:24:41 <kaz> s/wfiki/f2f wiki/
11:24:54 <kaz> ... alexa for voice interaction
11:24:55 <kaz> ... also PoC slides
11:25:11 <kaz> ... [Web of Things Roadmap - SHort Term]
11:25:23 <kaz> ... [Metadata Bridge]
11:25:30 <kaz> ... what we did
11:25:43 <kaz> ... read external metadata and translate into Wot TDs
11:25:54 <kaz> ... [Metada Bridge: Phase 1]
11:26:09 <kaz> ... many copies of leaf processor
11:26:37 <kaz> ... OCF HTTP bridge and OCF metadata bridge
11:26:41 <kaz> .. translate into TD
11:26:57 <kaz> ... (on the Gateway side)
11:27:23 <kaz> ... [Metadata Bridge: Phase 2]
11:27:25 <kaz> ... for Burlingame
11:27:54 <kaz> ... still have a meta data bridge
11:28:03 <kaz> ... traversal via NAT
11:28:17 <kaz> ... WoT Shadow Servient
11:28:22 <kaz> ... and Web Dashboard
11:28:31 <kaz> ... also would use Thing directory
11:28:47 <kaz> ... cloud is actually on my pc in this version
11:29:01 <kaz> ... update my metadata as RAML
11:29:07 <kaz> ... that's my minimum requirements
11:29:12 <kaz> ... [Voice Control]
11:29:54 <kaz> ... [Voice Control Burlingame WoT Plugfest, July 2017]
11:29:57 <kaz> ... impement Alexa Skill
11:30:03 <kaz> ... voice commands to actual skills
11:30:09 <kaz> .. back to the shadow servients
11:30:29 <kaz> ... Alexa Skill reads Thing directory
11:30:53 <kaz> ... local IoT devices superimposed
11:31:01 <kaz> ... that's I'm planning to do
11:31:09 <kaz> ... [Fog Integration]
11:31:22 <kaz> ... also thinking about this
11:31:35 <kaz> ... I have a proximity detector
11:31:44 <kaz> ... walking through a camera
11:31:58 <kaz> ... application I want to run
11:32:09 <kaz> make services discoverable and locally available
11:32:29 <kaz> ... would like to make CoAP working
11:32:38 <kaz> s/make/... make/
11:32:40 <kaz> q?
11:32:43 <kaz> ack m
11:32:44 <kaz> q+
11:33:06 <kaz> kaz: connectivity with the Fujitsu proxy?
11:33:33 <kaz> mm: local proxy has upstream and downstream
11:33:54 <kaz> ... not really clear about DS, AS, PS, etc.
11:34:12 <kaz> ... wondering we should add hyperlink for the detail of each entry
11:34:21 <kaz> ... URI for each device
11:34:38 <kaz> ... need to clean this up
11:34:56 <kaz> mjk: how to add information to the table
11:35:15 <kaz> mm: can work on the proxy side myself as well
11:35:38 <kaz> ... we need to take the information instead
11:36:00 <kaz> ... also wondering if we can make an effort to get tickets
11:36:04 <kaz> ... for encryption
11:36:30 <kaz> kaz: Matsukura-san, do you think Fujitsu also can try secure connection?
11:37:32 <kaz> ... if we can clarify the interface between Fujitsu proxy and Intel proxy, maybe those 2 pieces could be connected with each other
11:37:43 <kaz> matsu: should I add HTTPS as the protocol?
11:37:47 <kaz> mm: possible
11:37:54 <kaz> ... let's talk about that later
11:38:03 <kaz> ... some of the scenario I'm thinking
11:38:23 <kaz> mjk: common capability for those?
11:38:47 <kaz> mm: I have some particular scenario in my mind
11:38:55 <mkovatsc> q+
11:39:19 <mkovatsc> q?
11:39:24 <kaz> ack k
11:39:54 <kaz> kaz: we need to clarify possible scenarios from all the participants' viewpoint
11:40:06 <kaz> ... also wondering what kind of information is needed for the interconnection
11:40:13 <mkovatsc> http://plugfest.thingweb.io/
11:40:18 <kaz> mm: starting with adding a column?
11:40:54 <kaz> matsu: device servient for OCF device
11:41:08 <kaz> mm: WoT Proxy for HTTP
11:41:26 <kaz> ... don't want to have different protocols for WoT devices
11:41:43 <kaz> ... even though we need additional one for OCF devices
11:41:56 <kaz> matsu: expose Thing and consume Thing
11:42:14 <kaz> ... your devices are expose Things?
11:42:33 <kaz> mm: WoT proxy translate HTTP into CoAP
11:43:01 <kaz> ... might create a shadow servient which expose the capability using HTTP
11:43:21 <kaz> ... still consider these devices are participants of WoT
11:44:00 <kaz> ... we need concrete definition, though
11:44:21 <kaz> ... local proxy, remote proxy, shadow servient, Thing directory, etc.
11:44:47 <kaz> matsu: I think we'd like to concentrate on inter-Servient interface for the upcoming PlugFest
11:45:01 <kaz> ... so this might be out of scope?
11:46:00 <kaz> mm: we can have terms on what we mean
11:47:04 <kaz> kaz: think this is similar to Panasonic's setting
11:47:32 <kaz> ... McCool can expose the proxy servient which is connected to OCF devices
11:47:53 <kaz> mm: or the local proxy could be called as "OCF HTTP/CoAP bridge"
11:48:28 <kaz> matsu: the structure is similar to Pansonic's mechanism
11:48:59 <kaz> ... they have a translater between HTTP and Echonet on the local gateway side
11:49:02 <kaz> mm: agree
11:49:04 <kaz> q?
11:49:17 <kaz> ... logical way for OCF Things
11:49:37 <kaz> ... will upload this presentation on GitHub
11:49:59 <kaz> ... also would like to talk about the roadmap in long run
11:50:14 <kaz> ... incubation, WD, candidate, final
11:50:21 <kaz> ack m
11:50:38 <kaz> mk: question on [Metadata Bridge: Phase 2]
11:50:47 <kaz> ... one of the questions Matsukura-san made
11:50:53 <kaz> ... on synchronization
11:51:20 <kaz> ... how this connection between servients looks like?
11:51:45 <kaz> ... with proxy servient from Fujitsu, Panasonic or Siemens
11:51:57 <kaz> mjk: exposed Thing is servient
11:52:13 <kaz> mk: what is the existing connection?
11:52:25 <kaz> mm: create 2 devices
11:52:55 <kaz> mjk: how to open the tunnel?
11:53:01 <kaz> ... which pattern you choose?
11:53:09 <kaz> mk: one of the main challenges
11:53:35 <kaz> ... different parties bringing different mechanisms
11:53:40 <kaz> matsu: ok
11:54:00 <kaz> mjk: shadow servient goes through the NAT
11:54:25 <kaz> ... other servient talk with Thing directory?
11:54:34 <kaz> mk: you can't go through the NAT
11:54:46 <kaz> mm: the outside can't see the inside
11:55:11 <kaz> ... shadow servient can get information from Thing Directory but can't go back to the local side
11:56:08 <kaz> mm: Pansonic may have some solution
11:56:56 <kaz> kaz: we should document that issue as well
11:57:13 <kaz> ... maybe better to have an HTML or might be MD instead of PPT :)
11:57:42 <kaz> mjk: MQTT is another one
11:57:55 <kaz> ... this is good to start the discussion
11:58:05 <kaz> mm: the time is another issue...
11:58:31 <kaz> mjk: trying different mechanisms is good (for PlugFest)
11:58:54 <kaz> mk: Matsukura-san's initial expectation
11:58:57 <kaz> ... everyone can get on the same page
11:59:13 <kaz> ... but we already got interoperability issues
11:59:38 <kaz> ... put a link before
11:59:56 <kaz> rrsagent, make log public
12:00:00 <kaz> rrsagent, draft minutes
12:00:00 <RRSAgent> I have made the request to generate http://www.w3.org/2017/10/11-wot-pf-minutes.html kaz

12:00:11 <mkovatsc> http://plugfest.thingweb.io:8081/td
12:00:29 <kaz> mjk: people have different ways for NAT
12:00:45 <kaz> mm: you can't register URI behind NAT
12:01:21 <kaz> ... that's one of the reasons we need shadow
12:01:34 <kaz> ... should we continue the discussion?
12:01:48 <kaz> kaz: we should put issues on GitHub and continue the discussion next week
12:02:01 <kaz> mk: Matsukura-san should put the issues on MD
12:02:46 <kaz> ... and slides on the GitHub PlugFest area
12:03:09 <kaz> mm: and the table should go into the wiki
12:03:25 <kaz> mk: editing table on wiki is pain :)
12:03:37 <kaz> mm: ah, PPT is fine in that case :)
